It is a light but high-strength, easy-to-use, environmentally friendly material with wide application areas. It is a panel consisting of plywood tree layers. Although plywood has very good mechanical strength, it is a light material. The number of layers is usually produced as an odd number. The outer layers are generally parallel to the longitudinal dimension of the panel. Successive layers are glued perpendicular to each other. This type of production is a structure that increases strength and resists the shock effects that will occur with vibration. Plywood is a plywood material made from wood. Wooden layers are pressed with high pressure glue. It is covered with a waterproof film. The quality of plywood varies according to the hardness and durability of the wood layers used, the quality and amount of glue used, the pressure applied during the press and the quality of the phenolic film. The glue used should be WBP (Wheather Boil Proof). It makes it weatherproof for outdoor use. If the tree type used is Birch (Birch), it will be durable and robust. Varieties made of Vietnamese or Chinese poplar are also sold on the market. The applied pressure is important. It is one of the important factors that determine the quality of plywood together with the material used. One of the most important points to consider in the technical documentation while purchasing plywood should be the density of the plywood. There are also 450-500 kg/m3 ones. There are also 675 kg/m3 ones. Of course, there will be a price difference between them. You should make your choice according to your intended use. Plywood is a material that can be used again when it is cut. As you cut and drill, its wear will increase a lot. Using plywood where it needs to be cut can be expensive. Of course, it can be used if gross concrete is desired and this construction costs are taken into consideration. However, high quality plywood is not used for the places to be used by cutting. In the mold that you will make many times and without cutting or cutting but by creating a module, use the quality of the mold. If you buy cheap, you will have to buy it again and it will be more costly.
